Create a cozy, playful hand-drawn crayon illustration of three friends sitting on a caramel-brown sectional sofa in a living room, drawn with thick black sketch lines, rough wax-crayon texture, childlike proportions, and warm casual charm. Their faces are softly blurred or featureless beige rectangles for privacy. The left friend has long black hair, holds a large white rectangular sign with a black border, and wears blue pinstripe pants; the sign shows a bold red flame-style logo and the text STUDIO YAJA. The center friend has black hair, wears a black outfit with a red graphic on the chest, stands or sits higher in the middle, and raises both hands making peace signs. The right friend has long black hair, wears an all-black outfit, and holds a round black daruma doll with a cream face, red markings, flame symbols in the eyes and forehead, and orange lettering reading Yaja. The room includes exactly 2 visible lamps, one small yellow table lamp on the left and one tall white floor lamp on the right, exactly 2 brown sofa cushions on the right, yellow horizontal window blinds covering the background, a small bookshelf and plant on the far left edge, orange wooden flooring, and a round glass coffee table in the foreground reflecting red lettering. Use a cheerful snapshot composition, slightly wide angle, white paper background, energetic scribbled coloring, imperfect outlines, and a warm palette dominated by yellow blinds, brown sofa, black clothing, red logo accents, and blue pants.
